to the excavators mentioned in this documentation.
It is the responsibility of the owner(s):
!
to ensure local, regional and national regulations are observed,
!
to observe the bodies of rules (laws, regulations, guidelines, etc) stated in the operating instructions to ensure
safe handling of the equipment,
!
to ensure that the operating instructions are always available for the operating personnel and the information,
such as notes, warnings and safety rules and regulations, are followed in all points.
The data in the operating instructions apply for all models. Information applying only a certain model or only op-
tional equipment is highlighted e.g. (optional, KX057-4, U48-4 and U55-4).
The terms "front" and "direction of travel" refer to the view of the op-
erator when seated on the operator’s seat. Forward direction of
travel means that the dozer is at the front when driving forwards as
shown in the figure.
The symbols for operating and safety instructions are listed under "Safety symbols (page 15).
EC declaration of conformity
With the EC declaration of conformity, KUBOTA Baumaschinen GmbH certifies that the excavator
is in conformity with the valid standards and regulations at the time of marketing. The CE conformity
marking is located on the type plate and indicates compliance with the regulations.
If the excavator is modified or retrofitted without the approval of the manufacturer, the safety of the excavator may
be affected, thus invalidating the EC declaration of conformity.
The EC declaration of conformity is attached to the operating instructions for delivery of the excavator.
Keep the EC declaration of conformity in a safe place and show it, if requested, to the responsible authorities.
Should the EC declaration of conformity get lost, please contact your KUBOTA dealer.

or a local waste management contractor.
Noise emission and vibration
The values specified in this manual have been identified in the test cycle at an identical machine and are valid for
a standard equipment machine. The determined values are shown in the Technical Data (page 40).
Noise emission
The noise levels were determined using the method of determining the guaranteed sound pressure level of ISO
4871 based on directive 2000/14/EC, appendix VI.
The noise levels shown are not applicable for the determination of additional workplace noise emissions. The ac-
tual noise levels may need to be determined directly at the workplaces, subject to actually existing conditions (oth-
er noise sources, special operating conditions, sound reflections).
Depending on the actual noise emissions the owner must provide the necessary personal protective equipment
to the operator (ear protection).
Vibrations
The vibrations at the machine have been determined at an identical machine.
The vibration stress on the operator over a longer period of time must be determined by the owner at the site of
application, in compliance with directive 2002/44/ EC in order to consider individual magnitudes of influence.
Noise of a noise level of more than 85 dB (A) can cause hearing damage.
From a noise level of 80 dB (A), the use of an ear protection is recommended.
From a noise level of 85 dB (A), the operator must wear an ear protection.
